The Scot concedes Hunter's passing has been tough for everyone on the World Snooker Tour to take and revealed how the recent, tragic events have made him reassess the importance of the game in his life.

Higgins said: "It has definitely affected everybody in snooker and, although snooker players are not really your friends, rather they are acquaintances who you see at tournaments, to lose one of your close acquaintances is

heartbreaking.

"Paul was a top player for the last seven or eight years and obviously, during that time, we have been operating in the same circles at every

tournament.

"I was friendly with him and, while there were others who were a lot closer to him on the circuit, you are always in constant contact.

"It is a sad loss and, when something hits home such as what has happened to Paul, then you realise snooker is just a game that we are lucky enough to play."

However, Higgins initially altered his perception of snooker when his first son, Pierce, was born in 2001.

He added: "I have had a different perspective on snooker since I became a father five years ago because it is a singular sport where you are, in a way, very selfish.

"Obviously, it is always a big part of your life, but when you start a family your focus moves away from the table and you realise life is not just about snooker."

Higgins is the defending Grand Prix champion after defeating Ronnie O'Sullivan 9-2 in last year's final which took place at Preston's Guild Hall.

The 31-year-old is hoping to repeat his success when the first major tournament of the season begins at the Aberdeen Exhibition & Conference Centre on Saturday.

Higgins said: "To beat Ronnie convincingly in the final last year was a great result, which gave me a lot of confidence throughout the rest of the season.

"So it would be great to once again get off to a good start this year."
